SPRING-MOTOR FOR MECHANICAL LAMPS, 8L0.

SPECIFIOATION forming part of Letters Patent No. 448,208, dated March 17, 1891.

Application filed June 30, 1890. Serial No. 357,212. (No model.) i

To aZZ whom it may concern:

-Be it known that I, JOHN OAMIOHEL, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Spring-Motors for Mechanical Lamps and other Purposes, of which the following is a specification.

The object of my invention is to provide a series of springs by which the fan mechanism of a mechanical lamp or other mechanism may be operated, and which, while possessing the power of a heavy single spring, may yet be wound with much greater ease than can be the case where a single heavy spring is used in combination with a springbarrel in the usual manner.

I will describe in detail a mechanical-lamp mechanism embodying my improvement, and then point out the novel features in the claim.

In the accompanying drawings, Figure l is a vertical section of a mechanical-lamp mechanism embodying my improvement. Fig. 2 is a horizontal section of the same, taken on about the line 0: 00, Fig. 1. Fig. 3 is a view looking upwardly, the outside shell or case of the mechanism being removed. Fig. 4 is a detail showing the direction in which certain of a number of springs are wound. Fig. 5 is a similar view showing the direction in which certain of the other springs are wound. Fig. 6 is a detail showing how connection is made between certain of the springs of the series.

Similar letters of reference designate corresponding parts in all the figures.

A designates the outer shell or case, which may be cylindric, and is provided with supporting-legs a.

B designates an inner shell or case, which may also be cylindric, and is secured to the shell or case A.

O designates a main shaft provided below the case or shell B with a ratchet-wheel b, operated upon by a pawl b in an ordinary manner. By rotating this shaft in one direction certain springs D D, arranged within the case or shell B, may be Wound up. The lower of the springs D is secured at its inner end directly to the shaft 0, so that when said shaft is rotated the spring is coiled up from within. The outer end of the spring D is connected to the outer end of the spring D directly above it; or it may be made integral therewith in manner shown more clearly in Fig. 6, wherein two reverse folds are taken in the metal in such manner that one of the springs will be in a higher plane than the other. A portion of metal 0, connecting the springs D D, extends freely through a slot d, formed radially in a plate 0, through which the shaft 0 passes loosely, and which rests between the springs D D. The plate (2 may rotate freely. As the shaft 0 is rotated and the spring D continues to bewound up, its diameter is of course contracted and its continued winding causes the winding of the spring D. This will be readily understood from an examination of Figs. 4c and 5, in which it is seen that the springs D D are coiled in reverse directions. As the coiling of the spring D operates to rotate it in the direction of the arrow, Fig. 4:, it will draw with it the outer coiling of the spring D in the direction of the arrow shown in Fig. 5, and will consequently cause the coiling of the spring D from the outside.

The spring D is rigidly secured at its inner end upon a sleeve J, loosely surrounding the shaft U. Above the spring D, just described,

is another spring D, separated from the spring D referred to by another loose plate 6 without a slot d. The inner end of the second of the springs D is rigidly secured to the sleeve J. The second of the springs D is coiled in the same direction as the first of the springs D and in a contrary direction to the spring D. The winding up of the spring D tends to rotate the sleeve J in one direction, and as the second of the springs D is rigidly secured to said sleeve and said spring is coiled in a re verse direction to the springs D the coiling of the second of the springs D has a tendency to rotate the sleeve J in the other direction. The opposing forces therefore being equal, the sleeve J will remain substantially stationary.

The second of the springs D is connected to a second spring D in a manner similar to the connection between the first of the springs D D, and is separated from the second spring D by another of the plates e. The second spring D is connected near its inner end to a sleeve J, similar to the sleeve J, and to the sleeve J is connected another spring D. The operation of the springs connected to the sleeve J is similar to that of the springs connected to the sleeve J. The last-named spring D is connected to an upper spring Din manner similar to that previously described, said springs being separated by another plate 6.

The upper of the springs D is secured at its inner end to a loose sleeve J 2 on the shaft. The sleeve J 2 has rigidly mounted upon it a gear-wheel I, which gear-wheel meshes with a pinion I, from which is driven an ordinary train of gears operating a fan 1 by which air is forced upwardly to the flame of the lamp.

In this construction it will be observed, first, that adjacent springs are coiled in reverse directions, and therefore that alternate springs are coiled in the same direction; secondly, that the springs are arranged in pairs, being coiled in reverse directions, and,thirdly, that springs of different pairs, also coiled in reverse directions, are united to loose sleeves, which are prevented from rotation by the opposite coiling of the springs secured to the sleeves. By this construction and arrange ment the springs are wound in succession, commencing at the bottom, and each is partially wound before the winding of the next succeeding one commences. The lower of the springs is also wholly wound before the winding of the upper of the springs is concluded. The power necessary to wind the springs is therefore applied to each of the springs separately in a great measure, and

being thus distributed but comparatively little power is required to wholly Wind all the springs. The combined power of the springs will be equal to that of a single powerful coilspring combined with the usual spring-barrel, and which requires so much power to wind that feeble people and children are frequently unable to wind them.

I have illustrated and described six springs; but of course I may use any even number not less than four.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, in a springmotor, of a main shaft, a series of coiled springs consistin of two pairs arranged about the said shaft with the coils of each pair in different direc tions and connected together at their outer ends, of two sleeves loose upon the said shaft, one of said sleeves having connected with it the inner ends of the adjacent springs of the two pairs, the inner end of the spring at one end of the series being connected with said shaft and the inner end of the spring at the other end of said series being connected with the other of said sleeves, all substantially as herein set forth.

JOHN OAMICHEL.
